Abstract

The communication system in an embodiment includes a server apparatus. The server apparatus includes a controller that issues an instruction for executing priority control when a priority vehicle passes through a place where a roadside unit is installed. The priority control prioritizes a first communication performed by the priority vehicle via the roadside unit over a second communication performed by anything other than the priority vehicle via the roadside unit.

First claim

The invention claimed is:

1. A communication system comprising a server apparatus, the server apparatus comprising:
a controller that issues an instruction for executing priority control when a priority vehicle passes through a place where a roadside unit is installed, the priority control prioritizing a first communication performed by the priority vehicle via the roadside unit over a second communication performed by anything other than the priority vehicle via the roadside unit, wherein when the priority vehicle passes through the place, the controller issues an instruction for executing the priority control to the roadside unit, and
upon receipt of the instruction for executing the priority control from the server apparatus, the roadside unit performs the priority control.

2. A communication system comprising a server apparatus, the server apparatus comprising:
a controller that issues an instruction for executing priority control when a priority vehicle passes through a place where a roadside unit is installed, the priority control prioritizing a first communication performed by the priority vehicle via the roadside unit over a second communication performed by anything other than the priority vehicle via the roadside unit,
wherein when the priority vehicle passes through the place, the controller issues an instruction for executing the priority control to a priority-controllable communication network between the server apparatus and the roadside unit, and
upon receipt of the instruction for executing the priority control from the server apparatus, the communication network performs the priority control.

3. The communication system according to claim 2 , wherein the communication network includes a PON (passive optical network) access system that includes an OLT (optical line terminal) and an ONU (optical network unit).

4. The communication system according to claim 2 , wherein the communication network includes a PON (passive optical network) access system that includes a WAN (wide area network) communication network, an OLT (optical line terminal) and an ONU (optical network unit).

5. The communication system according to claim 1 , wherein when the priority vehicle passes through the place, the roadside unit transmits information indicating that the priority vehicle is approaching, to an apparatus around the roadside unit.

6. The communication system according to claim 1 , wherein the controller identifies the roadside unit installed at the place where the priority vehicle passes, based on a route where the priority vehicle is scheduled to pass and on an installation position of the roadside unit, and controls the identified roadside unit to perform the priority control.

7. The communication system according to claim 1 , wherein the controller issues an instruction for executing the priority control a first predetermined time period before an estimated time at which the priority vehicle is estimated to pass through the place.

8. The communication system according to claim 1 , wherein the controller issues an instruction for finishing the priority control a second predetermined time period after an estimated time at which the priority vehicle is estimated to pass through the place.

9. The communication system according to claim 7 , wherein the controller acquires the estimated time, based on a result of machine learning using past traveling data.

10. The communication system according to claim 1 , wherein when a distance between the priority vehicle and the roadside unit becomes equal to or less than a first predetermined distance, the controller issues an instruction for executing the priority control.

11. The communication system according to claim 1 , wherein when the priority vehicle moves a second predetermined distance or more away from the roadside unit, the roadside unit issues an instruction for finishing the priority control.

12. The communication system according to claim 1 , wherein when the priority vehicle passes around the roadside unit, the roadside unit controls a traffic light.

13. The communication system according to claim 1 , wherein the roadside unit causes a channel used for the first communication and a channel used for the second communication to be different channels, and performs the priority control by controlling communication on the channel used for the first communication to be prioritized.

14. A server apparatus comprising a controller that issues an instruction for executing priority control when a priority vehicle passes through a place where a roadside unit is installed, the priority control prioritizing a first communication performed by the priority vehicle via the roadside unit over a second communication performed by anything other than the priority vehicle via the roadside unit, wherein when the priority vehicle passes through the place, the controller issues an instruction for executing the priority control to the roadside unit, and
upon receipt of the instruction for executing the priority control from the server apparatus, the roadside unit performs the priority control.

15. A non-transitory computer readable medium storing a program causing a processor included in a server apparatus to function as a controller,
the controller issuing an instruction for executing priority control when a priority vehicle passes through a place where a roadside unit is installed, the priority control prioritizing a first communication performed by the priority vehicle via the roadside unit over a second communication performed by anything other than the priority vehicle via the roadside unit, wherein when the priority vehicle passes through the place, the controller issues an instruction for executing the priority control to the roadside unit, and
upon receipt of the instruction for executing the priority control from the server apparatus, the roadside unit performs the priority control.

16. A communication method of issuing an instruction for executing priority control when a priority vehicle passes around a roadside unit, the priority control prioritizing a first communication performed by the priority vehicle via the roadside unit over a second communication performed by anything other than the priority vehicle via the roadside unit, wherein when the priority vehicle passes through the place, the controller issues an instruction for executing the priority control to the roadside unit, and
upon receipt of the instruction for executing the priority control from the server apparatus, the roadside unit performs the priority control.

17. A server apparatus comprising a controller that issues an instruction for executing priority control when a priority vehicle passes through a place where a roadside unit is installed, the priority control prioritizing a first communication performed by the priority vehicle via the roadside unit over a second communication performed by anything other than the priority vehicle via the roadside unit, wherein when the priority vehicle passes through the place, the controller issues an instruction for executing the priority control to a priority-controllable communication network between the server apparatus and the roadside unit, and
upon receipt of the instruction for executing the priority control from the server apparatus, the communication network performs the priority control.

18. A non-transitory computer readable medium storing a program causing a processor included in a server apparatus to function as a controller,
the controller issuing an instruction for executing priority control when a priority
